384570000 | Split ring | 11 |
20090123104 | Needle Roller Bearing - A needle roller bearing comprises an outer ring having a plurality of outer ring members split by a parting line extending in the axial direction of the bearing, and a plurality of needle rollers rotatably arranged on the raceway surface of the outer ring. Thus, a non-contact length āLā between the outer ring members and the needle roller at an abutment part of the adjacent outer ring members, and an effective length āwā of the needle roller has a relation such that L/w<0.5. | 05-14-2009 |
20090142013 | Bearing apparatus - A bearing apparatus includes two split outer ring halves disposed in close contact with each other and a plurality of rollers. A circumferential end of each of the split outer ring halves has a concave-and-convex shape including a first slope portion inclined with respect to a line extending along an axial direction of the split outer ring halves and a second slope portion inclined in an opposite direction to that of the first slope portion. Each of the rollers is provided with crowning so as to be shaped in barrel form, and an amount of crowning is set such that an apex of a projecting portion at the concave-and-convex shape of each of the split outer ring halves is located on an axially outer side of a rolling surface of the roller rolling on an inner peripheral surface of each of the split outer ring halves. | 06-04-2009 |
20090154862 | Bearing apparatus - A bearing apparatus includes: two split outer ring halves which are mounted to the housing; a plurality of rolling elements which are provided so as to roll on the two split outer ring halves; and a cage which holds the rolling elements such that the rolling elements are disposed at substantially equal intervals in a circumferential direction of the cage and which is split at a position of the cage to form joint surfaces, an outside diameter of the cage being guided by inner circumferential surfaces of the split outer ring halves. An outside diametrical dimension in a normal direction to the joint surfaces is made larger than an outside diametrical dimension of the cage in a direction parallel to the joint surface, and vicinity of an outside diametrical position of the cage lying in the normal direction is made to be guided by the outer ring halves. | 06-18-2009 |

20130209019 | SPLIT BEARING RING AND ITS MANUFACTURING METHOD - A split bearing ring according to the invention includes two or more split portions into which the split bearing ring is divided with respect to a circumferential direction. Surfaces of the split portions other than circumferential end faces of the spit portions have hardness of HRC 59 or higher, the surfaces of the split portions other than the circumferential end faces are quenched and tempered, and the surfaces of the split portions other than the circumferential end faces have a prior austenite grain size of No. 6 or above. The split portions are formed by applying a load to a bearing ring such that stress generated on one end side of the bearing ring with respect to an axial direction is larger than stress generated on the other end side of the bearing ring with respect to the axial direction. | 08-15-2013 |
20130251298 | Rolling Element Bearing and Method of Making the Same - A method for manufacturing a rolling-element bearing includes forming an inner ring from a steel having a sulfur content of 0.002 to 0.015 mass % and an oxygen content of less than 15 ppm, subjecting the inner ring to a hardening heat treatment that ends by performing a final heat treatment step at a predetermined temperature, cold working the inner-ring raceway to generate compressive residual stresses at least in a surface layer of the inner-ring raceway, subjecting the inner ring to a bluing treatment and subjecting the blued inner ring to a thermal post-treatment process at a temperature below the predetermined temperature of the final hardening heat treatment step. The resulting rolling-element bearing may exhibit compressive residual stresses having an absolute value of at least 200 MPa at 0.1 mm beneath the outer surface of the inner-ring raceway and a maximum value of 1500 MPa or less throughout the inner ring. | 09-26-2013 |

20160025136 | SLEWING BEARING WITH SPLIT RING - The invention relates to a Slewing bearing having an inner ring and an outer ring, wherein at least the inner ring or the outer ring is formed as a split ring formed by combining a first split ring and at least one second split ring, wherein each of the split rings is provided with a plurality of mating through-holes and wherein the first split ring and the second split ring are joined by bolts fitted into pairs of corresponding through-holes. It is proposed that at least one of the through-holes in the first split ring has a larger bore diameter than the corresponding through-hole in the second split ring. | 01-28-2016 |
20160097425 | SEGMENTED OUTER RING FOR A BEARING FOR MITIGATING TORQUE DEGRADATION - An outer ring for a bearing includes an outer sleeve that defines a first exterior surface and a first interior area. The first interior area is defined by a first inner surface. The first inner surface has a first fastener mechanism formed therein. The outer ring includes an inner sleeve that defines a second exterior surface and a second interior area. The second interior area is defined by a second inner surface. The second exterior surface has a second fastener mechanism formed therein. The inner sleeve is removably disposed in the first interior area by selective engagement of the first fastener mechanism with the second fastener mechanism. The outer sleeve surrounds the inner sleeve and extends axially from a first end to a second end thereof. The inner sleeve extends from the first end to the second end of the outer sleeve. | 04-07-2016 |
